The stem-leaf plot is drawn in two columns separated by a vertical line. The number on the left hand side of the line represents the stem and the digit(s) on the right hand side represent(s) the leaf (leaves).

**Example: **

Consider the following data:

40, 42, 45, 49, 51, 54, 57, 58, 60, 63, 66, 66

Since the data is in ascending order, there is no need to sort again.

We observe that there are entries with 4, 5 and 6 in the ten’s place.

Þ 4, 5 and 6 become the stems.

**Let us plot the stem and leaf as follows**

4 | 0 2 5 9

5 | 1 4 7 8

6 | 0 3 6 6

- Here the leaves are from the unit’s place of the entries and the stems are from the ten’s place of the given entries.
- Repeated entries too, must be considered for plotting the leaves, as in the case of 66.
- Data should be represented in numerical order, and therefore it is best to sort the data before constructing the stem and leaf plot

- The number of digit(s) in a leaf in a stem-leaf plot is
- Two digits
- One digit
- Three digits
- Five digits

**Answer : B**

There is always one digit as this represents the tens of each number. - Which data set was the following stem and leaf plot taken from?

2 | 1 4 7 9

4 | 3 6 8 9

5 | 2 2 2 2

a. 21479, 43689, 52222

b. 21,479, 43, 689, 52, 222

c. 21, 24, 27, 29, 43, 46, 48, 49, 52, 52, 52, 52

d. 21, 24, 27, 29, 43, 46, 48, 49, 52

**Answer: C**

The stem represents the tens values, whilst each leaf is a unit value of the data set. Every value must be shown, therefore there were 4 lots of 52 recorded.
